Technical summary
The WordLift – AI powered SEO – Schema plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 3.54.10 via the JSON-LD REST API endpoints. The vulnerability is caused by the plugin registering JSON-LD REST API endpoints with a permission_callback of '__return_true' and the downstream converter retrieving the post via get_post() without verifying the post status or the requesting user's capabilities. This allows unauthenticated attackers to read metadata of private, draft, and pending posts by enumerating post IDs, bypassing WordPress core access controls.
Defensive priority
Defenders should prioritize verifying and remediating this vulnerability, especially for WordPress installations with sensitive content.
Recommended defensive actions
- Verify the WordLift plugin version and update to a patched version if necessary
- Restrict access to sensitive content and metadata
- Monitor for potential exploitation attempts
- Review compensating controls for exposed systems while remediation is scheduled and verified
- Check relevant monitoring, detection, and logs for exposed assets that need extra review
- Track exceptions, retest remediated assets, and close the item only after evidence is documented
- Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
Evidence notes
The vulnerability is caused by the plugin registering JSON-LD REST API endpoints with a permission_callback of '__return_true' and the downstream converter retrieving the post via get_post() without verifying the post status or the requesting user's capabilities.
